Beverage concentrate refers to a concentrate that is either in liquid form or in essentially dry mixture form. The liquid concentrate can be in the form of a relatively thick, syrupy liquid. The essentially dry mixture can be in the form of either a powder or a tablet. The beverage concentrate is usually formulated to provide a drinkable beverage composition or a final beverage when constituted or diluted with water, either carbonated or non-carbonated.

Drink powders are suitable for constituting with water, carbonated or non-carbonated, a final beverage for oral administration.

A specific example of a hypotonic beverage is a rehydration drink.

In general, the beverage can further be characterized in having an osmolality of from 50 to 800 mOs/kg, preferably from 150 to 600 mOs/kg, more preferably from 200 to 400 mOs/kg.

An isotonic beverage is typically characterized by an osmolality of from 270-330 mOs/kg.

The beverage further can comprise carbohydrates (C), proteins, peptides, amino acids, antioxidants, fats, vitamins, trace elements, electrolytes, intense sweeteners, edible acids, flavors and/or mixtures thereof.

Actually beverages can be prepared wherein the complete dry substance of the carbohydrates present in the beverage is consisting of isomaltulose, trehalose or isomaltulose, trehalose and said carbohydrate (A), preferably in a weight ratio of isomaltulose, trehalose to carbohydrate (A) from 30:70 to 90:10, preferably from 30:70 to 80:20. In a more preferred embodiment, at least one intense sweetener and/or at least one polyol can be added. More preferably the carbohydrate (A) is either sucrose or fructose.

Beverages wherein the dry substance of the carbohydrates is consisting of 50% (w/w) isomaltulose, trehalose and 50% (w/w) fructose, give the same sensory perception as a standard sucrose based beverage. Actually beverages wherein the dry substance of the carbohydrates is consisting of 51% (w/w) isomaltulose, trehalose and 49% (w/w) fructose, and wherein the weight ratio of isomaltulose to trehalose is 50:50, give a good flavour perception and are comparable to a standard sucrose based beverage, according to the evaluation of a taste panel. Furthermore, it is seen that beverages wherein the dry substance of the carbohydrates 50% (w/w) isomaltulose, trehalose in a respective weight ratio of 50:50, and 50% (w/w) sucrose give good sensory perception.

The further carbohydrates (C) are selected from the group consisting of monosaccharides, disaccharides, gelling starches, starch hydrolysates, dextrins, fibers, polyols and mixtures thereof, whereby these carbohydrates are different from isomaltulose, trehalose and carbohydrate (A) and (13) as mentioned in the composition of current invention.

Starch hydrolysates are produced by the controlled acid or enzymatic hydrolysis of starch and can be subdivided into two specific categories, maltodextrins and glucose syrups and are characterized by DE number (dextrose equivalent). In fact, DE number is a measurement of the percentage of reducing sugars present in the syrup and calculated as dextrose on a dry weight basis. Maltodextrins have a DE number up to 20 whereas glucose syrups have an DE number greater than 20.

Dextrins are prepared according to the dextrinisation method. Dextrinisation is a heat treatment of dry starch in presence or absence of acid.

Gelly starches may include emulsified starches such as starch n-octenyl succinate.

The low-calorie fibers can be polydextrose, arabinogalactan, chitosan, chitin, xanthan, pectin, cellulosics, konjac, gum Arabic, soy fiber, inulin, modified starch, hydrolysed guar, guar gum, beta-glucan, carageenan, locust bean gum, alginate, polyglycol alginate.

At least 50% of the dry substance of said beverage is comprising a dry composition containing

-   -   a) isomaltulose and trehalose, or     -   b) isomaltulose, trehalose, and at least one intense sweetener         and/or a carbohydrate         -   (A) selected from the group consisting of fructose, sucrose,             invert sugar, polyol and mixtures thereof.

It further relates to a beverage wherein at least 80%, preferably at least 90%, more preferably at least 95% of the dry substance of said beverage is a dry composition containing

-   -   a) isomaltulose and trehalose, or     -   b) isomaltulose, trehalose, and at least one intense sweetener         and/or a carbohydrate         -   (A) selected from the group consisting of fructose, sucrose,             invert sugar, polyol and mixtures thereof.

Among the major physiological electrolytes are sodium, potassium, chloride, calcium, and magnesium. Further trace elements can be included such as chromium, copper, selenium, iron, manganese, molybdenym, zinc and mixtures thereof.

Among the vitamins one can range vitamin A, vitamin C, vitamin E, vitamin B₁₂, and the like.

The edible acids can be selected from phosphoric acid, citric acid, malic acid, succinic acid, adipic acid, gluconic acid, tartaric acid, fumaric acid and mixtures thereof. Preferably the pH range of the beverage is from about 2 to about 6.5.

The flavors are selected from fruit flavors, botanical flavors and mixtures thereof. Preferred flavors are cola flavor, grape flavor, cherry flavor, apple flavor and citrus flavors such as orange flavor, lemon flavor, lime flavor, fruit punch and mixtures thereof. The amount of flavor depends upon the flavor or flavors selected, the flavor impression desired and the form of flavor used.

If desired, coloring agents can also be added. Any water-soluble coloring agent approved for food use can be utilized for the current invention.

When desired, preservatives such as potassium sorbate and sodium benzoate can be added.

Gums, emulsifiers and oils can also be added in the beverage for texture and opacity purposes. Typical ingredients include carboxymethylcellulose, mono-di-glycerides, lecithin, pulp, cotton seed oil and vegetable oil. It further can comprise foam stabilizing agents such as yucca, or yucca/quillaia extracts.

The beverage may be prepared by mixing together all of the ingredients. The mixture is then dissolved in water and agitated until all the ingredients are dissolved. Dissolution may occur at ambient temperature but it may be necessary for the solution to be heated to temperature between 50-100° C. to get all the ingredients into solution. After the mixture having been adjusted to a desired pH, the beverage may be bottled, capped, and eventually pasteurized at about 75° C. for about 20 minutes, or the beverage may be before bottling continuously pasteurized for a few minutes.

One way to prepare the concentrate of the beverage would be to start with less than the required volume of the liquid solvent that is used to prepare the drinkable beverage. Another way would be to partially dehydrate the finally prepared drinkable beverage to remove only a portion of the liquid solvent and any other volatile liquid present.

Carbon dioxide can be introduced either into the water to be mixed with the beverage concentrate or into the drinkable beverage to achieve carbonation. The carbonated beverage can then be stored in a container, such as a bottle or a can, and is then sealed.

The current invention further relates to an isotonic beverage that is comprising isomaltulose, trehalose and sucrose wherein the weight ratio of isomaltulose, trehalose to sucrose is from 30:70 to 90:10, preferably from 30:70 to 80:20. Furthermore, said isotonic beverage can comprise at least one intense sweetener, isomaltulose, trehalose and sucrose wherein the weight isomaltulose, trehalose to sucrose is from 30:70 to 90:10, preferably from 30:70 to 50:50, more preferably from 30:70 to 40:60. In a further specification, said isotonic beverage is comprising at least one intense sweetener and/or a polyol or a mixture of polyols.

Furthermore, the current invention relates to a method of preserving (sustaining) the osmolality of a beverage, preferably an isotonic beverage, by replacing 20 to 90%, preferably 30 to 80%, by weight of sucrose with trehalose and isomaltulose. At least one intense sweetener and/or polyol or mixture of polyols can be added.

Osmolality is a count of the total number of osmotically active particles in a solution and is equal to the sum of the molalities (molality is the number of particles in a mass weight of fluid (mmol/kg)) of all the solutes present in that solution.

In an isotonic beverage the concentration of the carbohydrates is such that the osmolality (expressed in mOs/kg) is the same or is only marginally exceeding the tonicity (=measure of the osmotic pressure of a solution relative to the osmotic pressure of the blood fluids) of the blood. The osmolality of blood usually ranges from about 280 to 310 mOs/kg. The osmolality can be measured with an osmometer, which is a device measuring the osmotic pressure (for example measuring the osmolality by the freezing-point method).

The method of the current invention is particular useful for beverages at pH below 7, preferably at pH between 3 and 4, more preferably for beverages at pH between 2 and 3.

Surprisingly, it was found that by replacing sucrose completely or partially with a composition comprising isomaltulose and trehalose in a beverage, preferably an isotonic beverage, the osmolality is constant under acid conditions and the osmolality remains over time more constant then in isotonic beverages based upon sucrose as carbohydrate source. Actually due to the more stable osmolality, a higher amount of the composition comprising isomaltulose and trehalose can be added to the beverage and yet the tonicity is not increasing at acidic pH, and consequently a higher amount of energy can be provided, over a longer period.

Actually, the current invention relates to a method wherein the osmolality is preserved for at least one month at ambient temperature, preferably for at least 3 months.

Furthermore, the current invention relates to the use of a composition comprising isomaltulose and trehalose, or to the use of compositions comprising isomaltulose and trehalose and which is further comprising at least one intense sweetener and/or a carbohydrate (A) selected from the group consisting of fructose, sucrose, invert sugar, polyol and mixtures thereof.

More specifically, it relates to the use of trehalose and isomaltulose for preserving the osmolality of beverages selected from the group consisting of hypotonic beverages, soft drinks, sports drinks, hypertonic beverages, energy drinks, and isotonic beverages. In addition, it relates to the use of trehalose and isomaltulose to increase the storage stability of isotonic beverages.

The current invention has the following advantages:

-   -   The composition comprising isomaltulose and trehalose is a         suitable source of sustained carbohydrate energy release.     -   The composition comprising isomaltulose and trehalose and at         least one intense sweetener and/or a carbohydrate (A) selected         from the group consisting of fructose, sucrose, invert sugar,         polyol and mixtures thereof, is particularly useful as a source         of sustained carbohydrate energy release.     -   Said composition is digestible, and absorbable.     -   The composition is versatile applicable in solid, semi-solid and         liquid comestibles.     -   The comestible is suitable for athletics, diabetics, babies,         infants, elderly people and those requiring a special diet.     -   The comestible is suitable for people following a slimming diet         due to the modified perception of satiety or hunger.     -   Osmolality of beverages is very stable due to the addition of         isomaltulose and trehalose.     -   The composition comprising isomaltulose and trehalose is         particular suitable for preparing beverages, preferably isotonic         beverages.     -   The composition comprising isomaltulose and trehalose improves         the storage stability (constancy of tonicity).

The current invention is illustrated by way of the following examples.
